SHUTTLE SPINDLE.

Application filed February The present invention relates to an improvement in shuttle spindles.

The object of the invention is to produce a shuttle spindle of such form as to be adapted toreceivea number of cop tubes of different sizes andbobbins. To this end the present invention consists in the shuttle spindle hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating the preferred form of the invention, Fig. 1 is a sectional elevation of a shuttle showing the spindle in place; and Figs. 2, 3, 4;, 5 and 6 illustrate different forms of cop tubes and a bobbin adapted to be carried by this spindle.

The illustrated embodiment of the invention is described as follows: The spindle or skewer 10 is pivotally mounted in the shuttle 11 in the usual manner. The spindle is provided at its base with cop tube holding ridges or threads 12, and at or near its center with another set of cop tube holding ridges or threads 13. At its end it is reduced in size and screw-threaded at 14 to receive a tip support- 15. The cop tube holding ridges or threads 12 and 13 are formed by rolling a helical groove in the body of the spindle, thereby pressing some of the metal out of the spindle body up into a thread or ridge. This ridge is sharp-edged and constitutes convenient and efficient cop tube holding means. The ridges or threads are preferably projected slightly beyond the surface of the body of the spindle, as shown, but it is to be understood that a depression in the body of the tube, that is to say, a groove in the surface, would constitute efiicient cop tube holding means by reason of the fact that the soft material of the cop tube would enter the groove and thereby secure the tube to the spindle. Vhile the ridges or threads are shown as of screw or helical formation, it is within the purview of the invention that these threads or ridges should be of other form.

The spindle with the cop tube tip support removed, as shown in Figs. 2 and 6, is adapted to receive a small cop tube 16, such as that shown in Fig. 2, or a bobbin 17 such as shown in Fig. 6. In the former case, that is to say, in the case of the cop tube. shown in Fig. 2, the cop tube holding ridges at the center of the spindle are those which engage and hold the cop tube. In the case 15, 1926. Serial No. 88,177.

of the'bobbin shown in Fig. 6, the latter is held in place by the usual bobbin retainer 18. The spindle arranged with the cop tube tip support in place, as shown in Fig. 3, is adapted to receive a somewhat larger cop tube 19, and in this case the tube is supported by the cop tube tip support, and it is retained on the spindle by engagement of the base of the cop tube with the cop tube holding ridges 12.

Referring to Fig. 4, it will be seen that the spindle is adapted to carry a cop tube 20 larger than that shown in Fig. 3, which is held in place by the threads 12 on the base of the spindle.

A still larger cop tube 21 is also adapted to be supported on the spindle, as shown in the illustration in Fig. 5.

The spindle has a. tapered base 22, a tapered blade 23 and a reduced screwthreaded tip 14. The tapered base 22, pro vided with the cop tube holding ridges or grooves 12, adapts the spindle to receive any cop tubes the bases of which are adapted to engage the ridges or grooves of any part of the base of the spindle. Thus, it is shown as engaging and holding cop tubes 19, 20 and 21 of diflerent sizes, which slide on to the base, each to a greater distance than the preceding one.

The spindle or skewer of the present invention is thus seen to be adapted to efficiently receive and carry a. Variety of cop tubes. lVhereas heretofore with each different cop tube a different spindle has been re quired, the present invention contemplates a single spindle adapted to receive and adequately carry a wide variety of cop tubes and a bobbin as well.

Having thus described the invention, what is claimed is:

1. A spindle or skewer for shuttles having an enlarged tapered base provided with cop tube holding grooves, a blade provided between its ends with cop tube holding grooves, and a reduced end portion to receive a cop tube tip support.

2-. A cop tube spindle or skewer for shuttles comprising an enlarged base provided with cop tube holding grooves, and a removable cop tube tip support so as to adapt the spindle or skewer to receive and properly support cop tubes of different sizes.

3. A cop tube spindle or skewer for shuttles having an enlarged tapered base provided with cop tube holding grooves, a

tapered blade provided with cop tube holdyond the tapered portion a reduced end provided with a removable cop tube tip sup port secured on the reduced end of the spindle, said base being provided with cop tube holding portions.

5. A spindle or skewer for shuttles of tapered form having a plurality of separated 15 cop tube holding ridges, a reduced'end portion beyond the tapered portion of the blade, and a removable cop tube tip support carried by the spindle end.

In testimony whereof I have signed my 20 name to this specification.
